Abstract

Program Kuliah Kerja Nyata (KKN) ini bertujuan untuk meningkatkan pengetahuan masyarakat Desa Bandar Dawung, Tawangmangu, tentang manfaat tanaman bunga telang (Clitoria ternatea L.) dan sereh wangi (Cymbopogon citratus) dalam menurunkan kadar gula darah, serta memberikan keterampilan dalam mengolah tanaman tersebut menjadi produk teh herbal dan permen jelly. Kegiatan ini dilakukan melalui metode penyuluhan, demonstrasi, dan pelatihan. Evaluasi keberhasilan dilakukan dengan mengukur tingkat pemahaman peserta sebelum dan sesudah kegiatan melalui pre-test dan post-test. Hasil menunjukkan bahwa pemahaman peserta meningkat hingga 90% setelah kegiatan. Selain itu, para peserta menunjukkan antusiasme dalam mencoba produk olahan tersebut sebagai alternatif terapi diabetes. Meskipun kehadiran peserta hanya mencapai 60% dari total undangan, program ini dianggap berhasil dalam memberikan kontribusi positif bagi kesehatan masyarakat. Program ini juga membuka peluang usaha baru bagi masyarakat melalui pemanfaatan tanaman lokal.

Abstract

Adsorption of methyl orange (MO) using epichlorohydrin cross-linked humic acid/cellulose composite has been carried out. This study aims to synthesize epichlorohydrin cross-linked humic acid/cellulose composites, determine the optimum pH, contact time, and initial concentration and study MO desorption. The adsorbent production begins with the isolation of cellulose from empty palm oil bunches (EFB) obtained from North Sumatra and the isolation of humic acid from peat soil obtained from Rawa Pening. Then humic acid was cross-linked to cellulose in an alkaline solution (NaOH), then epichlorohydrin was added as a cross-linking agent while heating at 600C for 2 hours. Epichlorohydrin cross-linked humic acid/cellulose adsorbents (AH/Cell-ECH) were further characterized using FTIR, XRD and SEM spectroscopy. MO solutions before and after adsorption were analyzed using UV-Vis spectrophotometry. MO desorption studies used HCl pH 4, 0.1 and 1.0 M NaCl and 40% and 60% ethanol. FTIR characterization showed that the AH/Sel-ECH adsorbents had active groups, including –OH, -C=O, and –COOH. Characterization using XRD showed diffraction peaks in the 2θ region around 11.41, 20.25, 22.55, and 42.66o, indicating the presence of galactose, xylose, glucose and polysaccharide phases. The SEM-EDX results showed that the surface of the adsorbent had non-uniform pore sizes, and the surface morphology tended to be clean and free of debris. It indicated the presence of C, O, and N elements in AH/ECH-cells and S, N elements after MO adsorption. The optimum interaction of AH/Sel-ECH with MO occurred at pH 2 with 150 mg/L MO, and a contact time of 120 minutes was obtained. MO adsorption by AH/ECH-cells followed a pseudo-second-order kinetics model and the Freundlich isotherm with an MO adsorption capacity of 9.84 x 10-5 mmol/g, respectively. Desorption studies showed that 60% ethanol was the most effective solution for desorption of MO.
